Polarization Maintaining

description

These polarization maintaining fibers utilize industry-standard, circular stress applying parts (SAPs) to create two axis in the core, each of which guides light at different velocity.
Polarized light launched into either axis will remain polarized as it is guided.
Precise alignment of PM fibers is absolutly essential for high performance splices. This dual circular SAP design allows easier alignment of the polarization axis when splicing two fibers or making components. Fiber reference must be chosen according to operating wavelength.
Standard coating is 400 μm diameter. For small packaging a smaller coating of 245μm or even a micro fiber of 80μm cladding with 165μm coating can be selected.
